Specification ol' LettcglsPatcnt.

Be it known that 1 Join; ll. Commas. a .1

citizen of the United States. residing at Cleveland. in the county ofCuyzhoga and State of Ohio, have invented a certain new and usefulImprovement in Detachable Links, of which the following is a full,clear, and exact description.

The object of this invention is to provide a detachable link capable ofbeing opened at both ends to permit of its ready connee-- tion to anddisconnection from other Links or rings or the like, but which, whenclosed. is securely locked against accidental displacement of the partswhich will permit either end to open.

The invention is especially intended for use as a means for quicklyconnecting or disconnecting two parts of fishing tackle. as, forexample, aswivel and a hook, but. it is also adapted for a variety ofother use In the drawing, Figure l is an elevation of my improved linkin its best form when closed. Figs. 2 and 3 are respectively transversesectional views on lines 2'2 and 3 3, of Fig. 1. Fig. 4 is an elevationof said link shown in Fig. 1 .when open at. both ends. Fig. 5 is anelevation of a modified form of the invention when closed; and Fig. (3is an elevation showing the same form of the invention when opened. Fig.7 is a transverse scctional view on line 7-7 of Fig.

Referring to the parts by letters A. represents an elongated link formedot spring wire bent into substantially the form shown. One side of thelink is parted to form the two spring tongues a, a.

B represents a lock in the form of a sleeve permanently embracing theside a of the link and capable of freely moving lengthwise thereon, saidsleeve being adapted also to, embrace the ends of the two spring tonguesa, a and hold them closed. In the flat trout of the sleeve B is alongitinlinal slot 7) extending from the lower end for about half thelength of the sleeve. Fig. 4 shows the link when open at both ends. Toclose it, the tongue a is sprung inward and the sleeve pushed up oversaid tongue. Then tongue at is sprung inward and intro duced into thesleeve through the slot '1') therein. Said tongue is then allowed tospring outward in said sleeve. der to prevent this locking sleeve .trommoving lengthwise of the link and thereby aceidentally releasing one orthe other of the Now, in or- I DETACHABLE LINK.

'ing shoulders which prevent the sleeve from moving endwise otl' of thisend of the link. The loop or eye (17 at the lower end of the link isalso formed, as shown, so that it is wider than the hole through thesleeve 13. It will be understood from the foregoing, therefore, thatwhen once the sleeve 15 is placed in the described position embracingthe side of the link, it is not possible at any time to remove ittherefrom. The loop o prevents the sleeve from moving downward oil ofthe lower end of the link. The loop a. prevents it from moving upwardoll' ol? the upper end of the link, and likewise prevents any suchmovement upward as will permit the lower end of the sleeve from movingpast the upper end of the spring tongue u.- The shoulder or shoulders o,0" or a, as the case may be, prevents any such downward movement of thesleeve when it. is embracing both spring tongues as will free the upperspringtongue a. It will also be noted in Figs. 1 and lthat the side a otthe link is also providedv with an outwarllly bent kink or shoulder(11". This is perhaps not essential, but it does help to prevent thedown and endwise movement of said sleeve upon the link, and likewise.

makes the link symn'ietrieal and therefor: more satisfactory for itsintended use.

In the form oi the invention shown in Figs. 5. (S and 7 the wiret'ormii'ig the sides of the link are not. bent outward to formshoulders, but, instead, the required shoulder is formed by anenlargement a on the. spring tongue 0- in a position to engage with thelower end of the sleeve. may be formed by upsetting the wire, or by adrop of solder secured thereon or in any other way. In other respectsthe device is substantially like that shown in Figs. 1 and l except thatthe lower end of the sleeve ll at the left side of the slot 5 is bentaround the side a so as to hold it in proper operative pos ion thereon.

This enlargement Having described my invention, 1 claim: 1. A detachablelink comprising a single piece of wire bent to form an elongated linkhaving one side parted to formtwo flexible "tongues and having widenedout loops at both ends, combined with a sleeve-like lock .of the linkwhereby the removal of the locking sleeve from the link is not possible.

2. A detachable link comprising a single *piece of wire bent to form anelongated link having one side parted to tor-m two flexible tongues andhaving widened out loops at both ends,-conibined with a sleeve like lockeeao e embracing and slidably mounted upon the unparted side of'thelink, and having in its side a slot throughwhich the lower tongue may beintroduced. into the embrace 'of'said sleevefi-the width" of said sleevebeing less than the width of the two loops at the ends of the linkwherebythe' removal of the locking sleeve from the link is not possible,and the lower spring tongue havin a shoulder in position to engage withthe lower end of said sleeve when the same is embracing both springtongues. a v r In testimony whereof, I hereunto afiix niy signature inthe presence ofvtwo. witnesses.
